Traction Pad Inspection

2
00:00:01,875 --> 00:00:06,458
Ensure that the pads are seated in the truck frame and properly retained.

3
00:00:06,458 --> 00:00:25,417
In a proper installation, the pads are compressed by approximately 0.62 inches (15.7 mm), and the rubber is bulged upward by approximately 0.125 - 0.5 inches (3.18 - 12.70 mm).

4
00:00:25,417 --> 00:00:32,417
Inspect the traction pads for extreme wear or severe separation of the rubber and steel laminations.

5
00:00:32,417 --> 00:00:38,708
Replace any defective or displaced traction pads as directed in the Backshop Manual.

6
00:00:38,708 --> 00:00:40,000
Dampers

7
00:00:40,000 --> 00:00:46,458
Visually inspect the dampers for signs of any oil leakage, dirt or droplets, and sweating.

8
00:00:46,458 --> 00:00:48,792
Lateral and Yaw Dampers

9
00:00:48,792 --> 00:00:55,208
Inspect each lateral and yaw hydraulic damper for leakage or defective rubber mounting bushings.

10
00:00:55,208 --> 00:00:59,250
A light film of hydraulic fluid on the body is normal.

11
00:00:59,250 --> 00:01:08,417
If the body is wet with fluid, the mounting bushings are worn, or bindings are badly eroded or missing, replace the lateral damper.

12
00:01:08,417 --> 00:01:11,333
Vertical Hydraulic Dampers Inspection

13
00:01:11,333 --> 00:01:14,292
1. Clean the lower body of the primary damper.

14
00:01:14,292 --> 00:01:19,708
2. Visually inspect the lower body for clearly formed droplets of hydraulic fluid.

15
00:01:19,708 --> 00:01:25,625
3. Clean all the dampers around the locomotive and return to the first one to begin inspection.

16
00:01:25,625 --> 00:01:32,292
4. Inspect the damper mounting bushings for wear, binding, badly eroded or missing parts.

17
00:01:32,292 --> 00:01:37,667
5. Inspect the structure for cracks, missing sections, or severe beating.

18
00:01:37,667 --> 00:01:53,292
6. Replace the vertical hydraulic dampers, if any of the following are found during the visual inspection: Droplets of hydraulic fluid formed at the lower body, signs of wearing, binding, or badly eroded bushings and broken parts.

19
00:01:53,292 --> 00:01:56,125
Vertical Hydraulic Damper Replacement

20
00:01:56,125 --> 00:02:01,500
1. Remove all four bolts and washers from each set of damper mounting blocks.

21
00:02:01,500 --> 00:02:05,792
2. Remove and discard both used vertical hydraulic dampers.

22
00:02:05,792 --> 00:02:07,833
3. Install new dampers.

23
00:02:07,833 --> 00:02:22,583
4. Reinstall the bolts and washers on each set of damper mounting blocks, then torque the bolts to 312 ± 16 lb.-ft. (422 ± 22 Nm).

24
00:02:22,583 --> 00:02:24,833
Coil Springs Inspection

25
00:02:24,833 --> 00:02:34,542
Visually inspect the spring coils for breaks, cracks, vertical wear flats, deep nicks, gouges, or other signs of spring damage.

26
00:02:34,542 --> 00:02:43,083
If visible damage to the spring coils indicates that the useful life or performance of the springs may be limited, replace the springs.

27
00:02:43,083 --> 00:02:45,708
Equalizer Bar Damper Inspection

28
00:02:45,708 --> 00:02:47,667
1. Clean the lower body.

29
00:02:47,667 --> 00:02:53,542
2. Clean all the dampers around the locomotive and return to the first one to begin inspection.

30
00:02:53,542 --> 00:02:59,792
3. Perform a visual inspection of the lower body for clearly formed droplets of hydraulic fluid.

31
00:02:59,792 --> 00:03:06,208
4. Inspect damper mounting bushings for wear, binding, badly eroded, or missing parts.

32
00:03:06,208 --> 00:03:11,208
5. Inspect the structure for cracks, missing sections, or severe beating.

33
00:03:11,208 --> 00:03:13,958
Equalizer Bar Damper Replacement

34
00:03:13,958 --> 00:03:23,958
1. Remove the four bolts, nuts, and washers attaching the equalizer bar damper to the equalizer bar damper support bracket and the truck frame.

35
00:03:23,958 --> 00:03:27,458
2. Remove and discard the equalizer bar damper.

36
00:03:27,458 --> 00:03:29,417
3. Install a new damper.

37
00:03:29,417 --> 00:03:42,417
4. Orient the damper correctly by ensuring that the larger diameter upper body of the damper is toward the equalizer bar damper support bracket and the smaller diameter lower body is toward the truck frame casting.

38
00:03:42,417 --> 00:03:47,458
5. Ensure that “BELOW” is stamped on the bottom side of the lowest end of the damper.

39
00:03:47,458 --> 00:04:08,333
6. Reinstall the four bolts, nuts, and washers connecting the equalizer bar damper to the damper support bracket and the truck frame damper mounting block, then torque the mounting bolts.
